Thrilled by the arrival of his baby girl, Williams told how Coco is the “most chilled” baby he has ever known.
The Angels singer told The Sun: “It’s funny. The first baby you have, ‘Shh, it’s sleeping,’ then you hear someone coming in that closes the door and you run downstairs and you go, ‘Shh! The baby!’
“Then the third one, the televisions on, the kids are playing, the dogs are barking, the baby stays asleep and the world doesn’t end.
“I wonder if the baby is so relaxed because we are relaxed.”
Williams, who already shares five-year-old daughter Teddy and three-year-old son Charlie with his other half, told how there is no jealousy between the siblings.
He explained: “The kids are getting on really well with her, there’s no jealousy.
“In fact there’s just lots of love and cuddles and Teddy wants to feed her all the time. So that’s what’s going on.”
At the time, she shared and adorable picture of the family all holding hands.
She captioned the picture: “I spy with my little eye an extra little hand. So we have been keeping a very special secret! We are delighted to share with you that we have had a baby girl….welcome to the world Colette (Coco) Josephine Williams!!
“It has been a very long and difficult path to get here, which is why we have kept it on the down low. Family comes in all forms, and this little lady, who is biologically ours, was carried by an incredible surrogate mother, to whom we will be eternally grateful.”
Field went on to add that the couple were “over the moon” and “so blessed” for the surrogacy to have been possible.
